Abstract: Objective To investigate the cause and preventive measures of recurrent laryngeal nerve (RLN) injuries in thyroid surgery in malignant thyroid neoplasms. Methods One hundred and eighty-seven patients with malignant thyroid neoplasms were treated by surgery from January 1996 to January 2006.The relationship to RLN injuries of operative ways and RLN exposed or not during operation were the analysed major point of this paper. Results There were 18 cases RLN in all these 187 patients, the injury incidence of RLN was almost 1%(18/187)in all surgery patients in malignant thyroid neoplasms. The temproary RLN injuries incidence in malignant thyroid neoplasms was 83.3%(15 cases), and the permanent damage RLN incidence in malignant thyroid neoplasms was 16.7%(3 cases). Conclusion The incidence of injury of RLN is related with the patterns of thyroidectomy.Most of RLN was temparary injury, and permanent damage RLN was rare.The anatomy of RLN and indentification in the procedure of thyroidectomy could not be ovoid to the paralyisis of RLN. A good command of the neck anatomy and the variation of RLN as well as careful operation will provide the key to the prevention the RLN injury in thyroid surgery in malignant thyroid neoplasms.
